Sabitsuke nakago utsushi

[DoTanuki yokai]

Hi, i found this utsushi by Masahira that was made with an old looking nakago with artificial rust and i absolutly dont know what i should think about this.

Will this make problems getting papers some day ? Are there more smiths doing this ?

Many tosho are doing utsushi, but it's a good question whether they can ever be papered. I'd bet on the answer being yes, because smiths have copied each other for a thousand years, but I wouldn't bet on when.

Gassan Sadakazu 1st,  made a Utushi of a Sadamune, that went Juyo.

Any more recent? Jussi?

As long as it's signed with the smiths name I don't see any issue? The OP is signed "マサヒラ" on the mune, so it's fine to receive papers seeing it's clear what it is.
The issue lies with blades that are made to deceive or where there can be doubt, not with clear utsushi (how many Masamune Hocho utsushi are out there? Dozens)

 

BTW I had the chance of handing that Sadakazu I Sadamune utsushi - it's absolutely brilliant!

I didn't get to hold it, but I saw at the Juyo exhibt at the NBTHK.

Ok, i want to know your opinions about adding rust to a new blades nakago to make it look old even if its clear the balde is not old ?

Thanks

I have a Sadakazu utsushi of a Masamune that is papered.  I think that it is no problem as long as it was not done to deceive, but rather as a tribute.
